Good hunting knife may be a subjective call for each of us, but overall Iíd say,

(1) size and shape suited for the given task. Am I bonding out an elk or falay a fish? Iím of the mind the no one blade really does it all well. I personally carry two blades with me when hunting. Can ether do it all, sure, but not always easiest.

(2) stays sharp for as long as possible. I hate having to stop multiple times when dressing out game to resharpen.

(3) is easy to sharpen in the field. Too many times Iíve had guys bring me blades that are from super steel that are just about impossible to sharpen on stones. In my mind it doesnít make scenes to have a blade that requires a machine shop to get back to where you need to be. Blades get dull if you use them, thatís a fact of life. My luck usually runs that it happens out in the field , farthest from my bench.

People fight over carbon vs Stainless. I like both for different reasons. Both can give you a good blade, carbon does require you to be a bit more careful about your blade care.

I would carry a nice drop point blade made from a good steel like D2 or S30V with a 4 inch blade and 1/8 inch thick, if sharpening is a problem use a diamond hone as it will be if these steels are heat treated properly. Most people can't hand sharpen anyway so carry something you can sharpen with and make it diamond. I like a flat grind on my hunting knife, but that's just personal preference. A knife like this can cut up vegetables as well as dress out a deer without the big struggle a thicker knife would be and if you ever noticed, the best Chef's knives have a nice flat grind all the way to the spine or top of blade. Makes cutting chores around the camp kitchen easier.

My second knife would be a filet knife because if I'm camping I'm fishing. This knife would be about seven inches long and thin with a flat grind all the way to the spine. I don't care about flexibility so a bit stiff is my preference. I don't object to a hollow grind either on my filet knife and have made some. They tend to be stiffer than some like though. I also use D2 or S30V as both are abrasion resistant and can go through a lot of fish if properly heat treated.
Both knives would have a good sheath too. I make leather sheaths for all my knives as I like working with leather.

Just a side note, if you want to cut wood carry an axe or hatchet. No knife will do the job as well as the proper tool does.
